Tracking kernel 2.6.32 for OMAP3

Recently I am thinking about update kernel to 2.6.32 for 0xdroid.
Currently the kernel for 0xdroid is based on 2.6.29 tracking AOSP's kernel tree. But we see there seems some new improvement introduced for OMAP3 platform, like including Graphics, a restructured patch set of DSS2 by Tomi, and updated EHCI hcd (USB 2.0) and USB OTG.

Actually the effect of changing kernel form 2.6.29 to 2.6.32 for 0xdroid project is not huge, but we expect updated USB EHCI can get the real stability and 0xlab's kernel can be suitable for more devices. Besides this, 0xdroid's kernel should start to follow up 2.6.32 branch of AOSP's omap kernel tree as well. It looks the force of development has been migrated to 2.6.32 branch already.

Use android emulator to play music

試著用android emulator 來播放音樂,

第一步，讓emualtor掛上一個sdcard image，
先使用android sdk裡的 mksdcard 來產生一個image。

$mksdcard 512M sdcard_for_android.so
$emulator -sdcard ./sdcard_for_android.so

接著就是把media file丟進sdcard space, for example
$adb push beat.ogg /sdcard

此時執行Music, 似乎還看不到丟進去的file...?
adb shell 進去，把 system_server 砍掉，讓它重跑。再進去Music，應可看到丟進去的音樂檔。
$ kill 'PID of system_server'

播放，似乎沒有聲音，重新run emulator，這時加入oss audio backend。
$emulator -sdcard ./sdcard_for_android.so -scale 0.5 -audio oss

執行Music，播放.... enjoy the music for a while....


android果然跟平常使用的環境不太一樣啊~~
